Figure 7: Calculated slopes from the linear curve fit of the relative film dose–response curves for radiosurgery fields of 5, 7.5, 10, 12.5, and 15 mm diameter at 'dmax' using EDR2 film. The output factors for these circular fields were calculated by normalizing the slopes from the linear portion of the relative film dose–response curve to the slope of reference field, 10 cm × 10 cm
